/**
* {@link com.sun.xml.internal.ws.client.sei.MethodHandler} that handles synchronous method invocations.
* This is refactored from SEIMethodHandler.
* <p>
* This class mainly performs the following two tasks:
* <ol>
* <li>Accepts Object[] that represents arguments for a Java method,
* and creates {@link com.sun.xml.internal.ws.message.jaxb.JAXBMessage} that represents a request message.
* <li>Takes a {@link com.sun.xml.internal.ws.api.message.Message} that represents a response,
* and extracts the return value (and updates {@link javax.xml.ws.Holder }s.)
* </ol>
*
* <h2>Creating {@link com.sun.xml.internal.ws.message.jaxb.JAXBMessage }</h2>
* <p>
* At the construction time, we prepare {@link com.sun.xml.internal.ws.client.sei.BodyBuilder} and {@link com.sun.xml.internal.ws.client.sei.MessageFiller}s
* that know how to move arguments into a {@link com.sun.xml.internal.ws.api.message.Message }.
* Some arguments go to the payload, some go to headers, still others go to attachments.
